1. Saturated: maximum (stable) concentration
QUESTION:
If Figure A represents a saturated solution, Figure B can be described as A. unsaturated and less dilute B. unsaturated and less concentrated C. supersaturated and more concentrated
Saturated: maximum (stable) concentration
Supersaturated: more concentrated, but unstable
Unsaturated: less concentrated or more dilute
If Figure A represents a saturated solution, Figure B can be described as A. unsaturated and more dilute B. unsaturated and more concentrated C. supersaturated and more concentrated
PAUSE
CLICK
A saturated solution is one that has the highest possible stable concentration of solute particles.
CLICK It is possible to have a higher concentration of solute particles, but the solution would be unstable. Over time, the solute particles will come out of the solution as a solid.
If we examine Figure B, it is obviously is less concentrated compared to Figure B.
So choice C is incorrect.
CROSS OUT choice C
Figure B does not represent a supersaturated or more concentrated solution.
Choice A is also wrong. The word dilute is the opposite of concentrated. A less dilute solution is more concentrated.
CLICK Choice B is correct. Figure B represents a solution that is less concentrated…. Or more dilute…. compared to the
solution represented in Figure A. Since the solution in Figure A is saturated, we refer to the solution in Figure B as unsaturated.
